The most widely used aluminum 6061 is fabricated into everything from pipe fittings and containers to automotive and aerospace parts.

Black anodized aluminum finish.

Anodizing creates a non conductive protective coating. The items below are designed to assist you in your choice of architectural aluminum finishes. You will have to be the judge as to whether or not this type of anodic coating will work for your particular application. Kawneer offers anodized painted or powder coated finishes in a wide range of color choices.

Techmetals has over 50 years experience in titanium and aluminum anodize assisting a variety of industries like the medical aerospace and automotive fields for instance. Anodized aluminum finishes can give your extrusions a chic professional look not only improving the aesthetic but also the performance. There are some who maintain that it can be applied over smooth anodized surfaces as well. In addition to the reasons above aluminum anodizing also offers some aesthetic benefits.

The market for architectural aluminum products demands a greater variety of finish types and colors than ever before. Prior to the development of this new blackening process black anodizing had been the only viable blackening option for manufacturers of aluminum components. The process is called anodizing because the part to be treated forms the anode electrode of an electrolytic cell anodizing increases resistance to corrosion and wear and provides better adhesion for paint primers and glues than bare metal does. Anodizing is an electrolytic passivation process used to increase the thickness of the natural oxide layer on the surface of metal parts.

It is strong and corrosion resistant plus it s easy to machine and weld. To achieve maximum corrosion resistance anodized particles are boiled in a solution of nickel acetate which effectively seals the component. While the anodized finish is extremely durable the process is so complex that only those who specialize in it can operate it properly and consistently. Clear and black finishes are also known as decorative anodize.

An anodized coating bonds to the aluminum surface to improve wear and corrosion resistance. Aluminum component parts that have been welded will show some discoloration on the welds after it is anodized even if the component has been. Anodizing can be done on a range of materials but today let s look at aluminum. Contact eagle mouldings for more information about our aluminum anodizing services at 1 800 888 2044.

The anodizing of aluminum is a popular process that improves the metal s durability resistance to corrosion and scratching. A common application of this type of finish is fluoropolymer coated hard anodized aluminum cookware.
